Answer:
Explanation:
In case of parallel lines, slope is same as that of the given line hence,in first equation ie y=-1/3x-7 slope is -1/3 and in second equation ie -y=6x+1 slope is -6
In case of perpendicular lines,products of slopes is -1.Therefore in first equation ie y=5/2x-1 slope is 5/2 then slope of perpendicular line turns out to be -2/5 and in second equation ie y=-7x+3 slope is -7 then slope of perpendicular line turns out to be 1/7
